4.4.1.2 Power level alignment
Following optical alignment, an alignment based on the received power level of each terminal should be
done. Use a voltmeter and cable with a banana jumper connector to attach to the bulkhead receptacle
connector on the terminal. Follow points 2 to 9 of the procedure for optical alignment to obtain maximum
voltage from each terminal.
A power level of -60dBm is better than a power level of -70dBm
4.5 Grounding
The terminal must be properly grounded.
Two screws are provided on the rear housing of the
terminal to facilitate the correct grounding. To fasten
the grounding cable onto the terminal, use a lug and
serrated washer combined with an M8 nut.
Connect the terminal to the connection points
nearest to the building-to-earth ground point. The
grounding conductor must be as short as is practical
and should not exceed 6 m (20 ft). For installations in the USA, refer to Articles 830 of the National
Electrical Code (Network- powered broadband communications systems). For installations in all other
countries, refer to the safety standards and regulatory requirements.
4.6 Lightning / Surge protector
Athena Wireless strongly recommends the use of outdoor data line protectors.
To protect humans and property, a lightning/surge protector must be installed before the power cable
enters the building.
4.7 Power injector
The power injector is connected in-line with the data line. The maximum
distance between the PoE injector and the A060-Mini
®
link is 100 m (328 ft)
The PoE injector must be IEEE 802.3at compliant (PoE+). To check that the
injector is functioning correctly, use a PoE Tester.
